Chapter 3 General Management of the Switch 3-115
■Ingress filtering only affects tagged frames.
■If ingress filtering is disabled, the interface accepts any VLAN-tagged frame if
the tag matches a VLAN known on the switch (except for those VLANs
explicitly forbidden on the port).
■If ingress filtering is enabled, the interface discards incoming frames tagged for
VLANs that do not include the ingress port in their member set.
■
Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP
or STP.However, they do affect VLAN dependent BPDU frames, such as GMRP.
■GVRP – The configured state of GVRP for the interface. GVRP must be globally
enabled for the switch before this setting can take effect (page 3-45.) When
disabled, any GVRP packets received on this port are discarded and no GVRP
registrations are propagated from other ports. The default is disabled.
■GARP Join Timer – The interval (between 20 and 1000 centiseconds) between
transmitting requests/queries to participate in a VLAN group. The default is
20 centiseconds.
■GARP Leave Timer – The interval (between 60 and 3000 centiseconds) a port
waits before leaving a VLAN group. Set this time to more than twice the join
time. This ensures that after a Leave or LeaveAll message has been issued, the
applicants can rejoin before the port actually leaves the group. The default is
60 centiseconds.
■GARP LeaveAll Timer – The interval (between 500 and 18,000 centiseconds)
between sending out a LeaveAll query message for VLAN group participants and
the port leaving the group. This interval should be considerably larger than the
Leave Time to minimize the amount of traffic generated by nodes rejoining the
group. The default is 1000 centiseconds.
■VLANs on Selected Port – The port is statically assigned to the specified VLAN.
■Membership Type – The port’s static VLAN membership type.
■Tagged:The interface is a member of the VLAN. All packets transmitted by the
port on this VLAN are tagged, that is, carry a tag and therefore carry VLAN or
COS information.
■Untagged: The interface is a member of the VLAN. All packets transmitted by
the port on this VLAN are untagged, that is, do not carry a tag and therefore
do not carry VLAN or COS information.
■Forbidden: The interface is forbidden from automatically joining the VLAN
through GVRP.See “Automatic VLAN Registration” on page 3-40.
■Remove: The selected interface is removed from the VLAN.
